In the bid to make things even easier and jump onto the many possibilities of the internet, wireless printers were borne. These make it possible to eliminate all the cables associated with traditional printing, opting to go with a broadcasted signal instead. You connect to the signal via your phone or computer and send the file you want to print to the machine. It’s all fun and games until a hacker gains access to that network and intercepts all the files you send. HP’s security warning of their devices issued just this year illustrates the severity of the threat and the attention it requires. To counter this, the company recently set up a bug bounty of US$10,000 to engage security expert. If you have a Wi-Fi printer that can also be cabled, plug it in now.
